SPECIFICATION forming part of Letters Patent No. 784,836, dated March14, 1905.

' Application filed March 5, 1904. Serial No. 196,785.

To whom it may concern.-

Be it known that 1, DAVID D. CLARKE, a citizen of the United States ofAmerica, residing at Newcastle, in the county of Lawrence and dition bythe heat derived from such molten metal. Under these conditions itfrequently happens that the oil becomes heated to such a degree that itis burned, and the burned oil adhering to the plates damages or spoilsthem.

In carrying my invention into effect I arrange in that part of theapparatus containing the oil a series of water-pipes disposed on bothsides of the rolls through which the plates pass, and I provide waterinlet and outlet pipes connected to the pipes arranged in theoil-receptacle and force water through the pipes in such receptacle,whereby I am enabled to maintain the palm-oil at the proper degree ofheat necessary for a perfect carrying out of the tinning process.

My invention consist in the novel construction, combination, andarrangement of parts to be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a vertical sectional view of atinning-machine provided with my improvements. Fig. 2 is a verticaltransverse sectional view on the line a m of Fig. 1. Fig. 3 is a planview, part of the tin pot or vessel being broken away.

The tin is maintained in amolten condition in the vessel 1, which isprovided with the usual bell-mouth perforated conduit 2, by means ofwhich the plates to be tinned are directed to and through the partition3, which is formed with a slot 4, through which the plates are passedinto the extension 5 of the vessel 1. The extension 5 is enlarged from apoint in alinement with the top of the vessel l and contains rollers 66, arranged in pairs disposed one apart from the other, and in the lowerpart of the extension 5 a curved perforated conduit 7 is arranged, bymeans of which the plates are conveyed from slot in partition 3 tobetween rollers 6 6. These rollers are supported in bearings 6, whichare supported on brackets 6, which are secured to the top of the vessel1 and project down and into the vessel to support the bearing 6'. Uponone side of the rollers 6 6 is arranged a sinuous line of pipe 8, whichextends substantially from end to end of the rollers and from a pointnear the top of the ,upper pair to a pointabout on a level with thebottom of the lower pair of rollers, this line of pipe being so arrangedas not to interfere with or touch the metal, and upon the opposite sideof the rollers I arrange a similar line of pipe 9. The lower terminal ofthe line of pipe 8 is connected at 10 to a horizontal pipe 11, thatleads to a vertical pipe 12, that is connected to a horizontal pipe 13,leading to water-inlet 14, the latter being provided with a union-jointand stop-cock 16.

The sinuous pipes 8 are suitably braced by the rods 28 to the vertical.pipe 12, as shown. Sufficient space is provided between the verticalpipes 12 and the sinuous pipes to permit the insertion of a dipper,whereby the metal may be skimmed without removing the pipes. The line ofpipe 9 is connected at 1'7 with a horizontalpipe 18,that leads to avertical pipe 19, that is connected at to the inlet-pipe 14, and betweenthis connection 20 and the pipe 14E I provide a stop-cock, as designatedat 16, and upon the pipe 13 is located another one of these cocks 16 tocontrol the inlet to the line of pipe 8. The sinuous pipes are at tachedto the vertical pipes 19 by braces 29, and the horizontal pipes 11 18are, it will be observed, disposed in the same plane as the lowermostbend or leg of the sinuous line of pipes and on the outside thereof, thepurpose of this arrangement being to cause the incoming water to passfirst through the pipes 11 18, which are farther away from the rollersthan the sinuous lines of pipe 8 9, so that the water will be heated toa certain extent before it reaches the pipes 8 9 adjacent to the rollers6 6, such arrangement of pipes being devised for the purpose of avoidingthe possible chilling of the oil which surrounds the rollers, thischilling causing the metal to adhere or freeze on the rollers.

The upper terminals of the sinuous pipes 11 18 are connected by theirvertical branches 21 22 to an outlet-pipe 23, leading to a wastepipe24:. The rollers 6 6 are actuated by gearwheels 25,arranged on the endsof their shafts outside their bearings, and receive mot-ion from thepulley 26, to which motion is communicated from any suitable source.Each of the vertical pipes 12 and 19 and each of the vertical pipes 2122 is provided with a protective coating 27 at the point where thesepipes pass into and out of the palm-oil, the level of the latter beingindicated by the line 0 0, such protective coating being either formedintegral with the pipes, in which event it consists merely of athickening of the walls of the same, or it may be separately applied tothe pipes, as desired, the purpose of coating the pipes at this pointbeing to prevent the pipes from being eaten through by the action of thepalm-oil, which when heated attacks the iron of which the pipes arecomposed at 01' near the surface of the oil.

The operation of the above-described apparatus is as follows: The pot orvessel 1 is kept lilled with metal, which is maintained in moltencondition to or about the level of the dotted line T T of Fig. 1, andthe palm-oil floats on the surface of the molten metal in the extension5 and surrounds the rollers 6 and the water-pipes in said extension. Theplates to be coated are passed through conduit 2 to the slot 4 inpartition 3 into the conduit 7, by means of which they are guided to therollers 6, passing upwardly between the same and through the palm-oil bywhich the rolls are surrounded. The inlet-pipe 14 is connected to asuitable source of supply, and the cock 16 being open water is allowedto flow through the several pipes above described and lind exit throughthe pipe 23 to the waste-pipe 2a. The water coming into the extension 5first through the vertical pipes 12 and .19 and the horizontal pipes 11and 18 is heated to a degree suliicient to prevent it from cooling thepalm-oil adjacent to the rollers, causing the metal to adhere to adeleterious degree, and

by regulating the supply of Water through the cocks 16 16 1 am enabledto maintain the palm-oil at just the proper temperature re quired forthe successful accomplishment of the tinning process.

It will be observed from the foregoing description, taken in connectionwith the drawings, that I have overcome the disadvantage heretoforerealized from tinningmachines now in operation and have constructed amachine of the above type which will keep the temperature of thepalm-oil at any desired degree of temperature, and I have so constructedthis machine that all parts of it will be accessible to the manoperating the same, and while 1 have herein shown and described aspecific construction it is obvious that 1 may change the generalarrangement and construction of the pipes without departing from thegeneral spirit and scope of the invention.

Having fully described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is

1. In a tinning-machine, the combination with an oil-receptacle androllers arranged therein, of two sinuous lines of pipes arranged one oneach side of the rollers in said receptacle, an inlet-pipe andoutlet-pipe, both said lines of pipes being connected to common inletand outlet pipes and the outlet-pipe being provided with protectivecoverings arranged at the level of the oil in said receptacle.

2. In a tinning-machine, the combination with an oil-receptacle and withrollers arranged therein, of two sinuous lines of pipes, a pipe arrangedhorizontally on the outside of and spaced apart from and parallel to thelowermost line of each of said sinuous lines of pipes and connectedthereto, an inlet-pipe common to said horizontal pipes, said horizontalpipes being connected to said common inlet-pipe, substantially asdescribed.

3. In a tinning-machine, the combination of an oil-receptacle androllers arranged in said receptacle, with cooling-pipes arranged in saidreceptacle, inlet and outlet pipes connected to said cooling-pipes andprotective coverings arranged on said inlet and outlet pipes at thelevel of the oil in the receptacle.

In testimony whereof I. allix my signature in the presence of twowitnesses.

DAVID D. CLARKE.
